[en] The study of low-frequency plasma excitations, similar to the vortex fluid motion, is of great interest in the problem of plasma magnetic confinement since these excitations may result in anomalous transport phenomena. For a moderate-pressure plasma, the magnetic drift mode may be dominant in the low-frequency range. This mode is associated with fluctuations of electron current parallel to the magnetic field lines. The stationary magnetic fluctuation spectra are presented in the framework of the cubic direct interaction approximation. (author)
